Definitions

  • the invention relates to a device for controlling the flow of a fluid, housed in a thermostatic faucet.
  • the valve that controls the flow of hot and cold water to the shower head or the faucet head must handle not only the on-off function but also the mixing of the hot water issuing from a hot water source with the cold water issuing from a cold water source in order to obtain water mixed to the temperature desired by the user.
  • This control element automatically modifies the flow cross-sections of the hot water and cold water inlets into the mixing chamber by moving a piece that acts like a slide valve.
  • the sensitive element shuts off the flow cross-section of the hot water passage in order to prevent burns.
  • a device of this type therefore controls the mixture of hot and cold water by automatically modifying the flow cross-section of the hot water and the cold water passages into the mixing chamber located downstream.
  • each of the devices has a control element located on one side of the body of the faucet for one of them, and on the other side for the other.
  • the flow control device can be positioned upstream or downstream from the temperature control device.
  • the opening/closing control device is generally disposed upstream from the device for controlling the mixture of the hot and cold water, in order to insulate the thermosensitive element when the faucet is not in use.
  • control device consists in a set of washers pierced with holes that in the open position, positions one washer relative to the other so that the holes of one washer line up with the holes of the other washer.
  • the flow control device works in an all-or-nothing way, meaning that it does not have any intermediate position, and the principle of these faucets consists of completely opening or closing the water inlets without the capability to control the flow rate.
  • flow control may be provided, but this requires being able to modify the flow cross-sections of the hot water and cold water passages simultaneously, which requires complex hole shapes.
  • thermosensitive element drives of one of the three disks in rotation, constituting a flow control means downstream from the mixing chamber.
  • thermosensitive element modify the position of the slide valve that controls the temperature.
  • One of the objects of the invention is to obtain a device of the aforementioned type that specifically eliminates the aforementioned disadvantages.
  • the subject of the invention is a device for controlling the flow of a fluid from a faucet comprising:
  • thermosensitive element which, plunged into a so-called mixing chamber, adjusts the temperature of the mixed water by modifying the cross-sections of flow to the mixing chamber of the hot water issuing from a hot water inlet and the cold water issuing from a cold water inlet, and
  • thermosensitive element for the flow control device located on the same side of the body of the faucet that houses the control device, and on the opposite side from the outlet, this device being characterized in that the means for transmitting the rotation of the control element is coaxial to the thermosensitive element and this means is a rotationally guided jacket housing the thermosensitive element, this jacket being rotationally coupled with the control element of the flow control device by a first coupling means, and rotationally coupled with the flow control device by a second
  • FIGS. 1 through 3 three partial longitudinal sections of a control device
  • FIG. 4 an exploded view of a part of the control device.
  • a device 1 for controlling the flow of a fluid housed in a thermostatic faucet 2 .
  • This device specifically makes it possible to prevent burns in case of a sudden drop in the cold water pressure and is convenient to use because of the automatic adjustment of the outlet temperature of the water.
  • such a faucet with a thermostatic control element 3 comprises:
  • thermosensitive element 3 which, plunged into a so-called mixing chamber 6 , adjusts the temperature of the mixed water by modifying the cross-sections 7 , 8 of flow to the mixing chamber 6 of the hot water issuing from a hot water inlet 9 and of the cold water issuing from a cold water inlet 10 , and
  • control element 13 for the flow control device.
  • the flow control device 11 is disposed downstream from the mixing chamber and controls the flow cross-section of the so-called outlet 14 located downstream from the mixing chamber.
  • Flow control is obtained by means of two washers 15 , 16 disposed one on top of the other, each of which has at least one hole.
  • One ( 15 ) of the washers 15 , 16 is rotationally immobilized, while the other washer ( 16 ), called the moving washer, is rotationally guided and rotationally driven, at least indirectly, by the control element 13 of the flow control device.
  • These washers 15 , 16 are preferably ceramic.
  • each washer is pierced with two holes, which essentially allow the outflow.
  • control knob and element are located on the same side of the body of the faucet that houses the control device, on the opposite side from the outlet 14 so that the means 17 , 18 for transmitting the rotation of the control knob and element are coaxial.
  • They can also be coaxial to the sensitive element 3 .
  • the temperature control device is housed in a rotationally guided jacket 19 inside the body of the faucet, and this jacket 19 , which is rotationally coupled with the control element of the flow control device by a first coupling means 20 and rotationally coupled with the moving washer 16 by a second coupling means 21 , at least partially constitutes the means 17 for transmitting the rotation of the moving washer.
  • the flow control device is disposed immediately at the outlet of the temperature control device, without a connecting conduit, which allows for a reduction in the overall dimensions.
  • This jacket 19 has two lateral slots 22 that allow the water issuing from the hot water and cold water inlets 9 , 10 to enter the mixing chamber 6 via the hot water and cold water passages, whose cross-sections depend on the thermosensitive element.
  • the slots extend along nearly the entire circumference.
  • nonreturn valves 23 , 24 in the form of rings with a substantially V-shaped cross-section prevent the return of the fluid to the hot and cold water inlets.
  • annular chambers 25 , 26 delimited by the outer surface of the jacket, the inner surface of the housing of the faucet receiving the flow control device, and gaskets 100 , 101 , 102 .
  • the disk-shaped ceramic washers are mounted in a sleeve 27 , which sleeve, at least indirectly, has means 28 for detachably connecting with the jacket 19 housing the temperature control device.
  • the rotational driving and/or rotational locking of one piece relative to another piece is achieved, for example, by means of cooperating shapes.
  • a pin 29 passes through the wall of the sleeve 27 housing the ceramic disks 15 , 16 and one ( 29 A) of the ends ( 29 A, 29 B) of this pin penetrates into a cavity 30 of the ceramic disk, while the other ( 29 B) projects outward from the sleeve so as to cooperate with the body of the faucet, for example a notch in the body, thus rotationally locking the fixed disk inside the body of this faucet.
  • the disk For the driving of the moving disk 16 , which is located as close as possible to the mixing chamber 6 , the disk has, for example in its side 16 A that faces the mixing chamber, a recess 16 B that receives a boss 31 presented at least indirectly by the jacket 19 , which drives it in rotation.
  • the link between the moving disk and the jacket is produced by an intermediate ring 32 that is coupled with both the jacket 19 and the sleeve 27 .
  • the temperature control device and the disks can therefore be replaced without requiring the replacement of the entire assembly.
  • the presence of the jacket makes it possible to produce a cartridge, i.e. a pre-assembled piece comprising the temperature control device and the flow control device disposed one behind the other, which need only be slid into the body of the faucet and is therefore easily replaceable.
  • the diameter of the intermediate ring and the sleeve are quite clearly no larger than the diameter of the jacket.
  • Another advantage results from a possible enlargement of the mixing chamber, which allows a much better mixture of the hot and cold water because it prevents the formation of hot or cold streams, and hence a better control of the temperature.
  • the hot water and cold water inlets are embodied by channels that pass radially through the housing of the faucet.
  • FIG. 3 shows that the temperature control device 5 is placed at the end of a bore, resting against a supporting surface 110 .
  • the slide valve 5 A controls the inflow of hot and cold water.
  • the ring 32 Positioned in front of this temperature control device is the ring 32 that locks the temperature control device, to which the flow control device can be adapted.
  • the jacket 19 is extended on the other side of the part housing the intermediate ring by a jacket 19 A housing the stem for controlling the temperature setting.
  • the flow control element is attached to this jacket.
  • the system is easy to produce.
